Not so fast there :-)
In the stress tests, I've encountered almost silent
filesystem corruption. The filesystem reports errors
as attached below, but the file operations continue
without error, corrupting files in the process. At
no time did the RAID software report any problem, nor
did any reconstruction kick in.
Anyone have any ideas what might be going on? It doesn't
seem to be exclusively a 2.2.4 thing. I've seen similar
problems with 2.0.36-19990128.
The stress test script is attached so people can try
this out for themselves.
Kernel is SMP (but the 2.0.36 problems were on a UP
kernel).
Rich.
